What is gingival whitening?

Gingival whitening is a procedure that restores gums darkened by melanin pigment or external irritation such as smoking and metal prosthetics to a bright, healthy pink color.

Just as much as teeth, if the gums look dark or are heavily pigmented, the overall impression can change.

Especially in modern society, where aesthetics are important, the color of the gums has a big impact on confidence and appearance, so many people visit us to address this issue through gingival whitening.

Teeth whitening vs. gingival whitening

Teeth whitening mainly uses oxidizing agents (such as hydrogen peroxide), whereas gingival whitening uses lasers or chemical peeling to thinly remove the gum epithelium.

The causes of gum pigmentation include the following, and in such cases, gingival whitening may be considered.

✅ Gums that are dark due to genetics ✅ Changes in gum color caused by smoking or prosthetics ✅ Medication side effects (anticancer drugs, antimalarial drugs, etc.) ✅ Periodontal disease and inflammation

New Teeth Gingival Whitening

Methods for gingival whitening include laser procedures, chemical peeling, and abrasion using a bur.

Gangnam Leong Dental Clinic’s New Teeth gingival whitening is performed by using a dental bur to thinly remove the melanin pigment layer on the gum surface. We previously used lasers, but because additional treatment was often needed, we adopted the bur method, which can provide results with a single procedure.

Gingival whitening process

1️⃣ Oral examination

Before setting a treatment plan, we assess the condition of the gums through a basic examination and consultation, check for periodontal disease, and perform scaling to help prevent infection.

(**If there is a condition, the procedure is performed after treatment.)

2️⃣ Surface removal after local anesthesia

After injecting anesthesia into the gums, the pigmented gingival epithelium is removed with a dental instrument (diamond bur).

The procedure takes about 10 to 30 minutes for the upper and lower gums respectively.

3️⃣ Gum protection and soothing care

Depending on the case, after the procedure we apply a protective agent or prescribe pain relief medication.

4️⃣ Recovery and management

You will return to the clinic after 1 to 2 weeks to check the condition of the gums.

Gingival whitening effects and maintenance period

Gingival whitening is a relatively simple procedure that can produce immediate results, and once recovery is complete, the gums improve to a natural pink tone.

The maintenance period varies depending on an individual's lifestyle, but on average it lasts 2 to 5 years. It is best to avoid smoking and pigmented drinks (coffee/wine), and to be careful when using metal prosthetics.
